Speccaton of Letters Patent.

Patented Apr. 18, 1911.

Application filed September 16, 1909. Serial No. 517,967.

To aZZ whom it may concern.'

Be it known that I, FRANZ MELICHAR, manufacturer, suloject of the Emperor of Austria-Hungary, residing at Brandeis-onthe-Elhe, Kingdom of Bohemia, Empire of Austria-IIungary, have invented new and useful Improvements in Regulating Devices for Seeding-Machines, of which the following is a specication.

The present invention relates to seeding machines of that kind, in which the seeding is effected by scoop-disks, and has for its object to provide means for varying the size of the scoops in order to regulate the quantity of seeds according to need. For this purpose means are provided to move the disks toward or away from .each other in order to enlarge or diminish the capacity of the scoops for taking up the seeds. In order to attain the object in view the scoops are secured to the disks in such a manner that the scoops secured to each disk extend through openings of the opposite disk. Now, if the disks are moved away from one another the effective capacity of the scoops will be diminished, while by moving the disks toward each other the capacity of the scoops will be enlarged.

In the accompanying drawing I have shown my invention.

Figure l is a sectional front elevation of the adjusting device; Fig. 2 a side view thereof; Fig. 3 a plan thereof; Fig. 4 a cross sectional elevation on a plane passing through the shaft; and Fig. 5 is an elevation of the divided shaft with the scoop-disks thereon, showing the scoops carriedvhy said disks.

a, Z) is a divided shaft, consisting of two halves semi-circular in section and longitudinally movable against each other.

A, B are disks carrying the scoops, A being attached to one part a of the shaft and B to the other part Z9.

o, c are rings, one mounted on a and the other on Z).

CZ', CZ' are divided rings, inclosing the rings o, c in such a manner that if the rings CZ', CZ' are axially moved, such movement will he imparted to the said rings c, c. Now, as one ring o is mounted on the shaft part a and the other on b, the shaft parts will axially he moved against each other as soon as the rings CZ CZ', engaging projections of the rings c, 0 are axially moved.

e', e' are projections attached to the divided rings CZ', CZ' and connected by screws e", e". n, n is a hearing and Z an annular groove in the same. ZL is another ring, guided in the said annular groove and provided with a handle 'C' extending to the outside through a slot m in the said bearing. f, g are curved arrow-like pieces, which by means of screws Zc are screwed to the inner-side of the said ring Z1.. There are two such arrow-like pieces and each of the same possesses a triangular head f' and g respectively and a dovetailed end f" and g" respectively. They are arranged in a cylindrical plane (Figs. 2 and 3) and are guided in a recess Z' of the bearing n, a'. In order to prevent the said arrow-like pieces from lateral shift-ing, the recesses Z are provided at their outer ends with ribs Z, which possess in their central part grooves Z".

'v are small stops arranged on the projections e, e. The said stops o engage the grooves Z" and thus guide the projections c, e of the rings CZ', CZ', preventing the latter from rotation.

The arrow-like pieces f and g are cylindrically arranged around the interior of the ring Zz. in such a manner that the triangular heads are always opposite the dovetailed ends, thus forming parallel slanting slot's r, r (F1a 2)- 0, 0' are studs mounted on the rings CZ', CZ' and the rings CZ', d' are so arranged that their studs o, 0 are directly opposite each other and engage the said slots p, p.

The mode of operation of the device is as follows If the handle c' is moved into the position shown in Fig. l in dotted lines, the ring Zt is also moved and also the arrow-like pieces f and g. Now, as the studs o, o' of the divided rings CZ', CZ engage the slots I p, p formed by the arrow-like pieces, the said divided rings will also be moved and in turn the rings c, o, which are fast on the shaft-parts Ct and respectively. As all these parts are moved in opposite directions, also the shaft parts will be moved in opposite directions so that consequently the scoop-disks fast on the same will he moved toward or away from each other.

In order to show to what extent the scoopdisks have been moved in either direction and what space is open of the scoops there is provided an indicating device, connected with the rings CZ', CZ'. rIlhe same consists of tWo bars 7', s, movable one over the other and extending from slots in the bearing a. The bar r is provided With a scale, While the end of the other bar s has a pointed end which moves over the scale, as shown in Fig. 4. The divisions on the scale `correspond to the Width of the scoops.

Means may further be provided to arrest the said handle in any desired position of its stroke. l

I claim as my invention :f

1. In seeding machines having scoop-disks, scoops passing therethrough and supported thereby, and means for moving the disks towardv or away from each other, for diminishing "or enlarging the capacity of the scoops, lsi'ibstantially as described. y

2. In a seeding machine, a shaft, scoopdisks supported thereon, scoops secured to each disk and extending through openings in the other disk, and means for moving said disks toward or away from one another to vary the effective capacity of the scoops.

'3. In a seeding machine, a divided shaft having tivo parts axially 'movable With reference to one another, a 'scoop-disk supported on each shaft part, scoops secured to each disk and extending through openings in the other disk, and means for moving the shaft parts axially with reference to one another to move said disks and thereby vary the eiiective capacity of the scoops.

4. In seeding machines the arrangement of a divided shaft, means for moving the tvvo shaft parts axially with reference lto each other, scoop-disks arranged upon the said shaft-parts, 'one disk being mounted on the one shaft partand the other disk on the other part, a series of scoops, secured to one disk, another series of scoops secured to the for indicating the capacity of 'the scoops,

substantially as described.

6. In seeding machines having scoopdisks the combination of a divided-shaft a, ribbed rings c, c mounted on either part of the dividedshaft, Vmovable grooved rings i i d', d engaging 'the said rings c, c and capable of moving the same in a lateral direction toward -or away from each other, ring z. and arron7 like pieces f, g, mounted underneath the said ring 7L and above the said rings cl, (Z, stops o, 0 on the said rings (Z, d 'engaging the slots formed according to the arrangement of the arrow like pieces j, g, means for turning the ring 7L a certain distance vand for fixing it in a certain position, means for preventing the rings "cZ, d from rotation and means for indicating the capacity of the scoops, substantially as described.

In testimony whereof I have signed my i .i

name to this specification in the presence of tivo subscribing Witnesses. p
